This is a very well done graphic novel that feels more like a game due to the way time moves even when choices aren't being made. So, definitely more real game than VN, but it still has the trappings of a VN in terms of some of the very early game play.

Edit: Once it opens up into more freedom to move around and explore the features of this game truly distinguish themselves from the typical Adult VNs that are all over ItchIO. This is a game that stands out.

Anyway, definitely give it a try.
